Mandriva Linux Security Advisory 2007.210

Posted Nov 7, 2007

Authored by Mandriva | Site mandriva.com

Mandriva Linux Security Advisory - Integer overflow in the build_range function in X.Org X Font Server (xfs) before 1.0.5 allows context-dependent attackers to execute arbitrary code via (1) QueryXBitmaps and (2) QueryXExtents protocol requests with crafted size values, which triggers a heap-based buffer overflow. The swap_char2b function in X.Org X Font Server (xfs) before 1.0.5 allows context-dependent attackers to execute arbitrary code via (1) QueryXBitmaps and (2) QueryXExtents protocol requests with crafted size values that specify an arbitrary number of bytes to be swapped on the heap, which triggers heap corruption.

Gentoo Linux Security Advisory GLSA 200710-11 - iDefense reported that the xfs init script does not correctly handle a race condition when setting permissions of a temporary file. Sean Larsson discovered an integer overflow vulnerability in the build_range() function possibly leading to a heap-based buffer overflow when handling QueryXBitmaps and QueryXExtents protocol requests. Sean Larsson also discovered an error in the swap_char2b() function possibly leading to a heap corruption when handling the same protocol requests. Versions less than 1.0.5 are affected.
